Facing a problem establishing a connection with Postgres from k8s

[xxxsemyonxxx]

Pre issue-raising checklist

I have already (please mark the applicable with an x):

• [x] Confirmed this is the right place to raise the issue - only issues related to the Dockerization of the Pact Broker should be raised here. Issues related to the Pact Broker application itself should be raised in the Pact Broker project.
• [x] Upgraded to the latest Pact Broker Docker image OR
• [x] Checked the [CHANGELOG] (/CHANGELOG.md) to see if the issue I am about to raise has been fixed
• [x] Read the Troubleshooting page

Software versions

• pact-broker gem version: eg 2.3.1
• pact-broker docker version: eg 2.3.1-1
• OS: e.g. Mac OSX 10.11.5
• pact broker client details: eg. pact-ruby-standalone CLI v 1.23.0

Expected behaviour

Works locally in Docker as expected. When deployed, should act simillarly

Actual behaviour

Fails to start pact-broker app instance due the following error in k8s:

/pact_broker/vendor/bundle/ruby/3.2.0/gems/pg-1.5.5/lib/pg/connection.rb:696:inasync_connect_or_reset': PG::ConnectionBad: connection to server at "10.168.3.100", port 5432 failed: server closed the connection unexpectedly (Sequel::DatabaseConnectionError)`

Steps to reproduce

Provide a repository, gist or reproducable code snippet so that we can test the problem.

`FROM pactfoundation/pact-broker:latest

ENV PACT_BROKER_PORT_ENVIRONMENT_VARIABLE_NAME=PACT_BROKER_APPLICATION_PORT ENV PACT_BROKER_PORT=9292 ENV PACT_BROKER_DATABASE_ADAPTER="postgres" ENV PACT_BROKER_LOG_LEVEL="DEBUG" ENV PACT_BROKER_SQL_LOG_LEVEL="DEBUG" ENV PACT_BROKER_DATABASE_USERNAME="pact_broker" ENV PACT_BROKER_DATABASE_PASSWORD="xxxxxxxxxxx" ENV PACT_BROKER_DATABASE_HOST="pact-broker.xxxxxxxxxxxx.us-east-1.rds.amazonaws.com" ENV PACT_BROKER_DATABASE_NAME="pact_broker" ENV PACT_BROKER_PUBLIC_HEARTBEAT=true`

Relevent log files

Please ensure you set logging to DEBUG and attach any relevant log files here (or link from a gist).

Many people have have successful deployments on k8s, we provide an example in this repository and helm charts are held here https://github.com/pact-foundation/pact-broker-chart

I would imagine this to be a network configuration issue, where your database is not accessible to the network your pact broker application is running on. This is out of scope for support I am afraid!
